Other times, we encounter "half-height" peaks, which go up to 2^14-1 = 16383, indicating that 25% of the bits are being demodded incorrectly. Can you get phase information from those samples? If you plot IQ in your unit circle at 1 sample per symbol, do you get a correctly equalized waveform?

'lo all. We are trying to use the USRP with the new gmsk demod block, and are encountering some weirdness. To generate our GMSK signal, we are using an Agilent signal generator. BT=0.35, 125 ksymbols/sec, 2 samples/symbol, with a PN15 as the data source. We load the produced slicer.dat into Matl
